Your friendship could be based on lively communications: lots of loud words and arm-waving, even friendly arguments. You seem to amp each other up that way. At first, your friend will look up to you as if you have all the answers.
You might tell them a few things about who you are and what you believe in, and they'll take these pieces of information and use them to build up a larger-than-life image of you that simply doesn't reflect the person that you are. Something about you will encourage this in them -- this exaggerated thinking and overblown perception of reality. They'll project philosophies and expectations onto you that have no solid basis in who you truly are or what you can deliver, and the comedown could be difficult for both of you.
